Piston Rings

[Charlie Hatfield]

On a ENF707A engine, the original part number for piston rings was 353GC1466P1. Mack superceded that number to 353GC1522B. As usual none available thru Mack. Hastings shows part number of 2C5550, and they currently have none available. Have not been able to find any listings any where else. So my question is, If I needed a set, where and who might have some?

Seal Power? or are they part of Hastings?

There is a company named Egge Machine Co. that makes custom pistons and rings for old cars. They may be able to make rings for larger bores such as your Mack truck.

Email or call them with your requirements. Or possibly they could refer you to a company that does make bigger OD ring sets.

Have you tried NAPA?

Try this Hastings piston ring link also.

Charlie,

When I was working on my V-8, got some of rings from Mack. For the rest we called Perfect Circle, Hastings or somebody ( memory ain't working right now) with complete dimensions for each ring needed (not part number) and they were able to supply. Might give this a try if you haven't already.

Good luck!
